My car is overheating and it has done this a few times. It seems like coolant isnt getting cycled through the system. Steam or smoke comes from the top of the radiator on the driver side near the rubber tube. I can open the radiator cap and have nothing come out that way but when i put water in, the radiator makes a small pop noise and spits coolant out. The temp meter will go up and down but will eventually stay at the top and sometimes go past the highest point. I really need to figure out whats going on, this is my only means of transportation
